EXIF / JPEG metadata
by Alistair Grant Nov. 30, 2025

Nov. 30, 2025

Hi Everyone, As far as I can tell, JPEGReadWriter in Pharo 7 doesn't read (or write) the image metadata, e.g. title, keywords, exposure time, etc. Is anyone aware of a package that does? Thanks! Alistair

Seems that Pharo is a magnet for this kind of project. I've been writing one as well and using it to organize my research notes. Does anyone working on personal info mgmt tools want to talk offline? I expect we're running into some of the same issues, both conceptual and technical. Evan

WebDav and CalDav in Pharo ?
by CÃ©drick BÃ©ler April 13, 2022

April 13, 2022

Hi all, I do some experiments with iCal. For now I serve a full calendar over HTTP. Not bad, but it is read only. Iâd like to try CalDAV. I was looking for it, and also webDAV. Gofer it smalltalkhubUser: 'UdoSchneider' project: 'FileSystemNetwork'; configuration; load. #ConfigurationOfFileSystemNetwork asClass project stableVersion load: 'Webdav' Iâve found the project of Udo, but it doesnât load on P8. I think this is due to the stream refactoring. Right now the image hung. Iâll try maybe to load it manually. But I was wondering oof there were other alternatives ? TIA, CÃ©drick

Is there any way to display the Class Hierarchy as a Diagram or a indented list. Even for all the classes in a package will do. ----- cheers, Sanjay -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

pharo 8 - method versions - how to see author/timestamp?
by PAUL DEBRUICKER Feb. 8, 2021

Feb. 8, 2021

Hi - Sometimes I want to revert to older versions of methods e.g. from an hour ago. In the "Recent versions of MyClass>>#myMethod" dialog no timestamps or authors are present. How do I see those? Thanks Paul

Intermediate-Level Tutorials for Pharo
by tbrunz Aug. 12, 2020

Aug. 12, 2020

tl;dr: I have some ideas about more advanced Pharo tutorials, and I have an example that I would like to have reviewed/critiqued before I develop it any further. I've been thinking lately that it would be nice to expand the number of Pharo tutorials we have available. But rather than (or along with) creating more "beginner" level tutorials, I'd like to see some good "intermediate" level Pharo tutorials. I think that programmers who already know the Pharo syntax and messaging semantics could benefit from more advanced tutorials that demonstrate how to develop "real world" Pharo code for "real world" processing needs. What I'm talking about is something that assumes you know the language, the basics of the IDE (but not necessarily how to leverage its capabilities to aid development), and the basics of the foundation classes (but not its details). I'd like a tutorial for intermediate Pharo programmers who want to become experts with Pharo. Something that can show you how to apply the tools of the IDE and the features of the language and base classes to create solutions that solve complex problems. What does the community think of this idea? -Ted -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Extract-method refactoring erratic behavior in Pharo 8
by Esteban Maringolo Aug. 10, 2020

Aug. 10, 2020

Hi, I get, more often than not, a message indicating an "invalid source to extract", commonly with the "End of statement list encountered" explanation. In comparison, I can extract the same code in Pharo 4. Is there a reason why the "Extract method" refactoring is not working in Pharo 8 as it was in that or any other version? Thanks! Esteban A. Maringolo
